The cultures were raised from the stipe and
stroma portion of healthy, sun-dried and fresh
specimens. The specimens were first washed
with distilled water and then the tissue from
the stipe and stroma portion were cut with the
help of a sterilized blade. The bits of tissue (2-
3 mm) were taken up with a sterilized forceps
and dipped in 0.1% mercuric chloride solution
for 5-10 seconds. Now the tissue was placed
on filter paper to remove the excess moisture.
The small bits of Cordyceps tissues were then
transferred aseptically into the petriplates
containing potato-dextrose agar (PDA)
medium with the help of a sterilized forceps.
These were then incubated at 250C for at
least 8-10 days and observed regularly for
appearance of culture. The actively growing
mycelial colonies were sub cultured to obtain
pure cultures.
